Teensy Tips

[the_bastet]

So I am about to go buy a Teensy and some arcade buttons and a couple encoders. Any tips anyone can give me as I venture into this world of DIY midi control?

[ErikMinekus]

Do you want tips on which components to buy, or how to program the Teensy?

I would get the Teensy 3.2 and look at Sanwa or Seimitsu for arcade buttons.

On components and wiring to the teensy. I really want midi output to LED as one of the projects is a pad controller.

There are beginner Arduino tutorials that explain how to wire up and use buttons and single-color LEDs.

If you want use RGB LEDs, or just a lot of single-color LEDs, you can get for example the WS2803 and read its datasheet to see how to use it.

If you want to use a lot of buttons, get the 74HC595 shift register.

Thanks for the tip. Currently I am going to be running single color leds for the hotcue and loop pads. I will get into RGB as I get a little more experience under my belt.

My current project is a simple browse encoder with load and 3 hotcues for each deck to sit below the crossfader.
then two seperate controllers to sit in between the turntables and mixer. This will put the hotcues and loop buttons right at my thumbs while scratching/juggling/etc.

I am thinking about using either lighted arcade buttons or arcide buttons with a lighted ring.

Im almost done with the first one. Just got to program her and finish the enclosure. I went with pine, for now. Still working on the 3d print, model.

I understand how to code the midi inputs and LED output, but how do I make a shift button?

[ErikMinekus]

I believe it's best to use an interrupt, as shown on https://forum.arduino.cc/index.php?topic=50313.0.

Thank you Erik,

I got the shift button working. Now that I feel more comfortable, I ordered some arcade buttons and started working on the 3D print design.

Here is a mock up of what I'm aiming for, for the finished product. Let me know what y'all think.
